As soon as I pulled up to their garage this afternoon a whole team of people came to work on my vehicle. I was the only client there this morning. You could hear the technician calling out "right tire good" while someone else was checking my lights. It's such a breeze to get through here and the cost is affordable, For an oil change on standard Toyota Corolla was about $108. They also reset my dash to make sure my maintenance light was off. This will always be my go to for future oil changes!

They say 15 minutes but in reality, look at it as 20 minutes for your oil change in total (I timed it) and then potentially 15-20 minutes in addition if there's an existing car In front of you already too. Make sure to get the Groupon to save $20ish. You still have to pay recycling fee + tax but still worth it.

One of the attendants got me started on the paperwork almost immediately. By 10:55am, my car was already being inspected, and by 11:05am, everything was done. The total, including the state paperwork, was $58--about $15 less than what I paid for my last smog check at another shop. I was really happy with the quick turnaround and the price. Highly recommended! BONUS MATERIAL: - They are a STAR certified station. Smog check was $49.75 (with coupon found on their website) + $8.25 for the CA paperwork.

When I went to the dealer, they quoted really high price and added a bunch of unnecessary services. I was able to get an estimate from Vuong which was much more affordable, and it was great to be able to text back and forth to make sure I'm only getting the services I really needed. It was also super easy to make an appointment. They were able to get me in and out in the same day even with all the difference things being done to my car. It was also really convenient that they have after hours dropoff available. You just park your car in their lot, and they have a safe place to drop off your keys. This was helpful because I had some work meetings I had to take in the morning at the time they opened, so I was able to go in before they opened and drop off my car. Highly recommend Vuong and his team if you're in need of any maintenance or repairs for your car!

I would definitely go back for any other repairs I would need done.

Pulled in and was warmly greeted, they had me in and out very quickly and the price was very very reasonable. I had purchased the tires from Costco (they offer free repairs and rotation), but scheduling to get the vehicle in can be a very long wait. When you have to get it done NOW, yeah, it's worth paying a little to get it done immediately - and Big O took care of us with very little out of pocket...and quickly.

First time I came here was for a basic oil change, since then it has been about 3 years now trusting these guys. Ken is the owner, him and his team are quick to respond and have a great system when getting your vehicle worked on. They will send you a link with a break down of the work and cost before proceeding you will have to sign it. I had a couple of my trucks with an oil leak, their mechanic Jimmy is the man. He has fixed a couple of my trucks and I just couldn't be happier. If you are looking for a good auto service place this is the place you can trust. Give them a try and I promise you won't be disappointed. Thanks again Ken and your team for always taking care of me.

I couldn't be happier with the work they did. The shop is spacious and clean, and the staff is friendly and knowledgeable. I had the pleasure of working with Anthony, and I also met Ken and Jimmy--they were all great. Anthony took the time to explain the repairs my car needed. When I picked up my car, he went over all the completed repairs and was happy to show me the old parts after I mentioned that I was curious to see them. Scheduling an appointment was easy. The repairs were completed on time, and my car is running great now. It's a great feeling to have an auto repair shop that I can trust. I will definitely be coming back for future maintenance and repairs.
